MATCH AND METHOD OF MAKING THE SAME.

No Drawing.

To all whom it may concern Be it known that I, CHARLES L. GABRIEL, a

' citizen of the United States, residing at the city of New York, borough of -Brooklyn,'

Kings county, and State of New York, have invented certain new and useful Improvements in Matches and Methods of Making the Same, of which the following is a ful clear, and exact specification.-

' My invention relates to an improvement in matches and method of making the same, and it has for its object more particularly to provide a simple, effective and economical method of treating the match splint in order to render it non-glowing after the flame has been extinguished.

and end, my invention consists in the steps or treatment, constituting my invention,- hereinafter more fully described and then pointed out in the claims.

Matches as ordinarily made consist of thin I sticks or splints of soft wood which are first into a suitable mixture composed essentially impregnated with an agent such as paraflin in order to render the splint more readily ignitible, whereupon the splint is dipped of phosphorus, which when dry forms a combustible head on the end of the splint.

The making of matches according to the method briefly above outlined results'in the production of a match which will, after it has been ignited and its flame subsequently extinguished be provided with a splint which will glow or remain incandescent for an appreciable period or time. This afterglow of the burnt orcharred splint is frequently the cause of fire and other accidents, which might be prevented if the afterglow or incandescent state of the splint did not con tinue after the flame is extinguished- In ortreat the splint prior to its impregn impregnated with paraflin, with a solution consisting of a liquid hydrocarbon combined with an aromatic oil; or with a fatty acid; or with benzol, toluol, xylol, or similar Specification of Letters Patent.

bodies. This solution serves as a solvent in which I dissolve one per cent. (1%) oftrichlorid of phosphorus or pentachlorid of phosphorus.

By preference I form the impregnating solution by mixing about two pounds of benzol with about one pound of trichlorid of phosphorus, and then bringing the same to a temperature of about 78 O.,-and maintaining the same at said temperature for fifteen to twenty minutes. Hereupon I allow the mixture to cool, and when the same has cooled down to about atmospheric tem: perature I add the same to about one hun- If the impregnating is to be done with paraflin as a vehicle, instead of with liquidpetroleum, thesolution should. be heated to about the melting point of paraffin, 2'. 6. 100 C. in order to render the same fluid.

It is to be noted particularly that instead of combining an aromatic hydrocarbon with kerosene or petroleum. oil to form a solvent, I may substitute instead of the aromatic hydrocarbon one of the fatty acid compounds, or any similar body. Further it is to be noted that I may cause impregnatin material, viz: the trichlorid or pentachlorid of phosphorus to react on the solvent, viz: and enter into chemical combination therewith, thus changing the character of the solvent, or I may cause the impregnating material to react with the linseed oil, fatty acid, benzol, toluol, or xylol, and then add the resultant compound to the solvent as above described.

Having thus described my said invention, 7

whatI claim and desire to secure by Letters Patent is: V v

1. The method of preparing match splints which consists in impregnating the same with a solution comprising a phosphorus chlorid, a solvent therefor, and a. vehicle, substantially as specified.

2. The method of preparing match splints which consists in impregnating the same with a solution comprising a phosphorus chlorid, a solvent'therefor and a liquid hydrocarbon, substantially as specified. 3. The method of preparing match splints which consists in impregnating the same with asolution consisting of trichlorid of phosphorus dissolved in a liquid hydrocarbon, substantially as specified.

4. The method of preparing match splints which consists in impregnating the same with a solution consisting of trichlorid of phosphorus dissolved in benzol, and mixed with petroleum, substantially as specified.

5. The method of preparing match splints which consists in impregnating-the same with a solution consistin% of trichlorid of phosphorus dissolved in enzol and mixed with a petroleum derivative, substantially as specified.

6. The method of preparing match splints which consists in impregnating the same with a solution composed of trichlorid of phosphorus about one pound; benzol about two pounds, mixed with kerosene about one hundred pounds, substantially as specified.

7. A match splint formed of a suitable substance impregnated with a solution consisting of trichlorid of phosphorus dissolved in benzol, and a liquid hydrocarbon, substantially as specified.

8. A match splint formed of a suitablesubstance impregnated with a solution consisting of trichlorid of phosphorus dissolved in benzol and mixed with petroleum, substantially as specified.

9. A match splint formed of a suitable substance impregnated with a solution consisting of trichlorid of phosphorus, dissolved in benzol and mixed with kerosene, substantially as specified.

10. Amatch splint formed of a suitable substance impregnated with a solution consisting of trichlorid of phosphorus, about one pound; benzol, about two pounds mixed with kerosene, about one hundred pounds, substantially as specified.
